One of the fans injured when car parts flew into the grandstands at Daytona International Speedway Saturday tweeted a photo of himself Thursday and revealed that he was hit in the chest by a flying tire.

Becket McGinn, one of two fans still hospitalized at Halifax Health, has updated his Twitter profile to say, “Business Student. Big Sports fanatic. Yes I survived a NASCAR tire to the chest.”

McGinn tweeted Thursday: “So hard to sleep with all this rib damage. Just glad the tire didn't kill me.”

McGinn later tweeted that he has four broken ribs and that his 14-year-old brothers has a collapsed lung.

“I'm recovering at a relatively quick pace,” he tweeted. “My 14 year old brother is worse. … It hurt to laugh with 4 broken ribs but I do feel fortunate that I and my 14 year old brother are alive.”

McGinn said in a tweet to Sporting News reporter Bob Pockrass that he was knocked to the ground during the incident and that a fan nearby took off his shirt to stop his bleeding.

In a tweet to McGinn, another fan tweeted a photo of McGinn being helped by fans.

Three more fans injured in the crash Saturday were released from Halifax Health Thursday morning, leaving two fans still hospitalized from the more than 30 who were injured from flying debris.

Hospital spokesman Byron Cogdell said both patients who remain hospitalized are stable.

Fans were hit by debris after the car of Kyle Larson got airborne during the final lap of the Nationwide Series race. Larson’s car was ripped apart by the catch fence, with pieces of the car, a wheel and suspension pieces flying into the crowd.

McGinn, one of the fans who remain hospitalized, tweeted a photo earlier this morning of him and Nationwide Series driver Scott Lagasse, who visited the hospital earlier this week. He also tweeted a photo of him and Tony Stewart, who visited the hospital Sunday.
